Answer 1

the obvious

Explanation:

thx to the person above

Answer 2

Let us compute b

The linear model is now y=ax+b

y=6.36x+(-1.43)

y = 6.36x - 1.43

NOTE : Due to approximation issues during computation , we will make b= - 1.44 to agree with choices in the drop down . Hence our linear model will be ;

`y=6.36x-1.44`

first box : 6.36

second box : - 1.44
